I create my recipe files that I use in general, but then I have a folder for mixed juices.In that folder, I create a folder named the nic batch number,In that folder, I save the modified recipe for each customers specific juice, so I have record of it without changing the original recipe.

This helps me keep track of born on dates, and to know who to contact if I find anything later on about any part of a mix. Customer safety needs to be priority 1. So if you had a customer that thinks they may have gotten a stinky, or bad mix, you can easily track to see if any of the others from that group had similar issues. If you mixed it right (always a chance for problems) and nobody else had an issue, you can see if it was a product issue, or operator error very quickly.

Anyway, Hope this helps someone and any suggestions are always welcome

I've recently been seeing so many new vendors getting in too big of a hurry to mix juices and make that money! But fail to keep track of everything. Not taking nicotine handling seriously is a HUGE mistake and can cause e-cigs being banned in your area or others.

Not trying to sound like a fatalist, but just trying to show how I use your calculator to help me in my attempt to keep my records straight and be able to track what juices I mix with what batch of nicotine.

Yes, I will have loads of copies of the same recipe, but I will know what batch of nicotine it was made with and have a date it was made using "Save As" and keeping the files organized the best I can.

I have to agree! I work with allot of new vendors and try my best to help them be careful in developing a way to be safe and assure traceability so if they ever do find a problem, they can know who has what.

I've seen a few vendors take off way too fast and not even a care about safety or quality, just push the juice, scares the beegeebers outta me.
